Hi just something i dreamed up today
My barrel making setup is quite critical; the relationship between the partoff and turning tool is set in stone; the programs are all made to fit this distance; and while I do have to reset sometimes; i don't like to do it because I need to make just a few barrels that need a special shaped tool
Here is my solution
A piggy backed tool mount; this bolts to the front of the main tool post; it carries another 1/4" sq bit; you can see it's 11mm in more that the reg tool; I can still pass with the chuck for drilling etc



Just passing alonga good idea that saved me a bunch of time

The new tool carrier was made on the 4 axis; I even cut the tool slot 6.3mm deep and 8mm wide over 56mm long; not bad; the tool never moved; mindI was only taking 0.2mm cuts; but i just went out for lunch and it was done when i returned
